Building Thermal Insulation Market Summary

The global building thermal insulation market size was estimated at USD 26.9 billion in 2024 and is projected to reach USD 37.8 billion by 2030, growing at a CAGR of 5.9% from 2025 to 2030. The market is witnessing notable growth as insulation materials become increasingly essential in both new construction and renovation projects. Rising energy costs worldwide are encouraging homeowners, builders, and commercial developers to adopt insulation solutions that help reduce heat loss or gain within buildings. This not only lowers monthly utility expenses but also improves indoor comfort by maintaining more stable temperature conditions throughout the year.

Increasing residential and commercial applications of the product to reduce overall energy costs, coupled with rising awareness about energy conservation, are expected to drive market growth. Consumers are becoming more conscious of the environmental impact of excessive energy usage, leading to higher adoption of insulation technologies. Additionally, construction companies are incorporating insulation as a standard component to meet customer expectations for energy-efficient buildings. The shift toward sustainable living and green construction practices is also catalyzing the demand for advanced insulation materials capable of delivering long-term performance and durability.

Favorable regulations that focus on lowering overall energy consumption are likely to be a major factor driving the market for building thermal insulation. Many countries have enacted stringent building codes that require minimum insulation levels to improve overall energy performance. These policies encourage energy-efficient building designs and promote the adoption of high-quality insulation products in both public and private infrastructure. Thermal building insulation helps reduce dependency on Heat, Ventilation, and Air Conditioning systems by minimizing thermal transfer, thus reducing the need for continuous heating or cooling. This benefits consumers through reduced energy bills and contributes to broader environmental goals by lowering carbon emissions.

Key Market Trends & Insights

• The building thermal insulation market in Europe accounted for the largest revenue share of 34.9% in 2024. Europe’s dominance can be attributed to its strict energy efficiency standards, mature construction sector, and high awareness levels among consumers regarding sustainable living.
• By product, the glass wool insulation segment dominated the market with a revenue share of 37.1% in 2024. Glass wool is widely preferred due to its affordability, strong thermal performance, ease of installation, and fire-resistant properties.
• By end-use, the residential segment accounted for the highest revenue share of 53.2% in 2024. The growing emphasis on energy-efficient homes, along with rising renovation activities, is strengthening demand within this segment.
• By application, the wall segment led the market in 2024. Walls represent the largest surface area in buildings and therefore require extensive insulation to reduce energy loss, making them a primary focus for insulation manufacturers and construction professionals.
